How can an air suspension spring be determined to be defective?

Determining if an air suspension spring is defective often involves evaluating how the vehicle sits and behaves when on level ground. When a car leans to one side, it can indicate a problem with the suspension system, particularly the springs. An air suspension system relies on balanced air pressure within the springs to maintain proper ride height and load distribution. If one side is lower than the other, this could suggest a leak in the air spring or a failure in the system, leading to uneven weight distribution and compromised handling.

By observing the vehicle's stance, a technician can identify symptoms that may point to the air suspension spring being defective. While other methods, such as listening for unusual sounds, measuring air pressure, and checking for visible cracks, can provide supplementary information about the suspension system's health, the most immediate and visually apparent symptom of a defective air suspension spring is the noticeable lean of the vehicle on level ground. This acute observation is a straightforward way to diagnose potential issues in the air suspension system effectively.
